Configuring an Alarm Profile
This section describes how to configure a list of threshold values for error
states which can be applied to a selected group of ports.
Command Attributes
• Alarm Profile – Name of the profile. (Range: 1-31 alphanumeric
characters)
The default profile includes the default thresholds for VDSL lines.
• thresh-15min-ess – Threshold for Errored Seconds (ESs) that can
occur within any given 15 minutes. (Range: 0-900 seconds, where 0
disables the threshold; Default: 2)
An Errored Second is a one-second interval containing one or more
CRC anomalies, or one or more Loss of Signal (LOS) or Loss of
Framing (LOF) defects.
This parameter sets the threshold for the number of errored seconds
within any 15 minute collection interval for performance data. If the
number of errored seconds in a particular 15-minute collection interval
reaches or exceeds this value, a vdslPerfESsThreshNotification
notification will be generated. (Refer to RFC 3728 for information on
this notification message.) No more than one notification will be sent
per interval.
When this threshold is exceeded, notification messages are sent to
registered SNMP hosts as required by RFC 3728, reported to the syslog
system, and displayed on the console interface.
• thresh-15min-sess – Threshold for Severely Errored Seconds (SESs)
that can occur within any given 15 minutes. (Range: 0-900 seconds,
where 0 disables the threshold; Default: 2)
A Severely Errored Second is a one-second interval containing 18 or
more CRC-8 anomalies, one or more Loss of Signal (LOS) defects, one
or more Severely Errored Frame (SEF) defects, or one or more Loss of
Power (LPR) defects.
